摘要：以取代的苯甲酸乙酯和邻羟基苯乙酮为原料,合成了一系列含卤素取代氟硼二异吲哚类新化合物.这些化合物的结构均通过了1H NMR,HRMS,IR等手段的表征.通过紫外可见吸收光谱和荧光发射光谱测试,化合物均显示较长的紫外吸收及荧光发射波长.取代基对于化合物摩尔消光系数和荧光量子产率以及单线态氧生成能力有明显的影响,其中含CH3O和CF3取代的化合物6b和6f显示了更高的摩尔消光系数,而含Br取代的化合物6e显示高的单线态氧生成能力和中等的荧光量子产率.
The new boron diisoindolmethene compounds were synthesized from ethyl benzoate and 1-phenylethanone, and characterized by 1H NMR, HRMS and IR. These compounds exhibited the long UV-absorption and fluorescence emission wavelength. The effects of substituents on the molar extinction coefficient, fluorescence quantum yield and singlet oxygen yield were easily noticed, methoxy substituted compound 6b and CF3 substituted compound 6f showed the higher molar extinction coefficient than other halogen substituted compounds, and compound 6e containing Br substituent exhibited the higher singlet oxygen yield and the lower fluorescence quantum yield than other compounds.
